Problems solved by technology

With the emergence of the automatic line for precision forging blade processing, this detection method can no longer meet the needs of the production mode of "unattended, less human intervention", which is an automated production mode , in the whole processing process, the operator only needs to pre-install the parts to be processed on the fixture and place them in the predetermined position, and the rest does not need manual intervention, so the traditional detection method needs to be improved to adapt to the automatic processing line detection of precision forging blades

Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] see Figure 1-4 , The blade inspection fixture of the present invention includes a base 1 , a centering bush 2 , a threaded plug 3 , an eccentric shaft 4 , a push rod 5 , a threaded bush 6 , a handle 7 , a screw 8 and a positioning pin 9 . The base 1 is fixed on the EROWA pallet, and then the pallet with the detection fixture is installed on the EROWA chuck to ensure that the stacking axis of the blade to be tested coincides with the central axis of the EROWA pallet and the EROWA chuck. The EROWA pallet and EROWA chuck rely on pneumatic compression, and the EROWA pallet and testing fixture are fixed with screws. see Figure 5-8 , the centering bush 2 of the present invention is connected with the base 1 through the screw 8; the eccentric shaft 4 drives the push rod 5 to move up and down through the handle 7, so that the positioning surface of the bla...

Abstract

The invention discloses a detection fixture and a detection method for a dovetail-shaped rabbet rotor blade. The detection fixture comprises a base that can be mounted on an EROWA tray, and the EROWAtray is mounted on an EROWA chuck of an automatic processing line. The top of the base is provided with a catch groove for mounting the tail of the dovetail-shaped rabbet rotor blade, and a folded shaft of the dovetail-shaped rabbet rotor blades coincides with a central shaft of the EROWA tray and the EROWA chuck after being mounted. The base is provided with a hole in a direction of the central shaft of the EROWA tray and an ejector rod capable of moving up and down. The ejector rod can tighten the bottom surface of the dovetail-shaped rabbet rotor blade for fastening at one end, and is provided with an eccentric shaft at the other end. The eccentric shaft is transversely arranged on the upper portion of the base and can be locked through a positioning pin. A corresponding measurement program is arranged in a precision forging blade automatic processing line, and the automatic production mode of unattended operation and little human intervention can be achieved through interaction.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a detection fixture and a detection method for a dovetail tenon rotor blade. Background technique [0002] In the traditional three-coordinate inspection of precision forged blades, the inspector manually establishes a measurement coordinate system according to the benchmarks required by the drawings of the measurement fixture, and installs the blade in the measurement fixture for inspection. After the inspection is completed, the blade is disassembled, and the report is printed. Complete batch inspection of blades. With the emergence of the automatic line for precision forging blade processing, this detection method can no longer meet the needs of the "unattended, less human intervention" production mode. The "unattended, less human intervention" production mode is an automated production mode. , in the whole processing process, the operator only needs to pre-in...
